President Donald Trump scored another clean win in the Alabama runoff for the Republican nominee for Senate, and prediction markets traders read it the whole way.
Rep. Barry Moore won the runoff with nearly 56% of the vote against former Navy SEAL Jared Hudson. Moore’s win adds to Trump’s run of Senate successes, which recently include Louisiana and Texas, and reinforces that his endorsements have been much sturdier in Senate contests than in state-level races.
Prediction markets aligned with the outcome heading into Tuesday’s election. For prediction markets now, Alabama quickly becomes a non-event from here. Both Polymarket and Kalshi are pricing Republicans around 95% for November, but the general election contracts are barely drawing interest, with under $12,000 in volume on both platforms.
Trump keeps winning Senate fights
This is the kind of race that fits Trump’s stronger lane in 2026 politics. His Senate endorsements have generally translated into results, and Alabama was another example of the market following suit.
While polls pointed to a close outcome, the prediction markets hardly ever wavered in their backing of Moore. The runoff win matters as a signal, but mostly because it adds one more data point to the pattern that Trump’s Senate picks are doing better than his governor picks.
Moore’s also in a safer lane in Alabama than some other Trump-backed candidates, which Senate Republicans are concerned makes the general-election matchups more challenging.
The broader takeaway is that Trump’s endorsement still carries real weight when the contest is a Senate nomination in a deeply Republican state. That does not mean every race is competitive. It does mean his influence remains highly relevant where the GOP base aligns with him.
Prediction markets priced Alabama Senate win
Traders have essentially treated Alabama like a foregone conclusion. The Republican nominee contracts drew real activity, with $2.1 million on Kalshi and $426,000 on Polymarket, but the general election side is much quieter because there is little reason to expect a shakeup in November.
When both prediction markets sit at about 95% for Republicans and the volume is barely above a rounding error, the markets are saying the same thing most voters probably are: This race is settled before it starts.
The market can still be active on the nomination. Once the nominee is set, however, the general election fades fast.
No real November stake
Alabama does not carry much weight in the 2026 midterms or in Senate control.
The general election is unlikely to be competitive, so the seat is not the kind of toss-up that will shape the balance of power in Washington come November, like Maine or Georgia. The runoff and the market activity around it matter more as a barometer of Trump’s standing inside the GOP than as a genuine Senate battleground.
This is less about a pivotal election and more about a market-confirmed nomination win in a safe seat. Trump’s Senate endorsement machine still works.
